  • Problem-solving requires reconstruction, risk assessment, and perseverance.
  • Students also look at how critical and creative thinking were already applied to development and knowledge and how they relate to biological problems.

Ethical and Individual Understanding

  • Is applied across Units 1-4 in science. Ethical understanding enables a range of ideas.
  • Students must consider implications to their own findings/ investigations of living in a responsible decision-making setting.
  • VCE Biology can demonstrate applying appropriate ethical context. Units 1-4 can provide opportunity to help time/decicion making for others.
  • Students are required to participate, speak and share ideas as a contribution to scientific endeavours.
  • Students identify goals, set strategies and value, and use aid as feedback in both collaborative and individual settings.

Understanding Diversity

  • ATSI- Understand the diverse historys and social structure of how ATS peoples understand scientific thinking/ observe and test it using traditional methods.
  • Teachers promote ATSI acknowledge and provide design/ learning programs for students considering Koorie education ( state, national and regional) for including ATSI.

Use of Terms

  • VCE Biology explains how to use and interpret terms with specific consideration.
  • ATS peoples are the first people of Australia represented by language groups (territory/ country).
  • Those of strait islander culture annexed in Quensland in 1879 are also indigenous people and have 5 culture groups.
  • It is important to note those of Aboriginal descent who have lived with community and identification.
  • Country - traditional land by language group can encompass feelings of deep connection and attachment associated with it.
  • Major aims- explains that are supported by natural phenoma/ event.
  • Students also have the option of how to rely on data genration can "conclude" for themselves and ask. 'Does the differences indicate a changing scale''
  • To study this the accuracy of a measurement needs to relate to how close the quantity is being measured. It's important to make this clear.

Additional Points

  • Validity- Validates what has been studied. Has experimented and what claims can investigated.

Ethical and Safety approaches to Biology

  • Ethical issues support- support students and identify bioethical issues and to explore issues with context. They depend and give advice.
  • Consequences- is primarily used for maximising postive outcomes; duty has people and the means to reach these ethical stages.

Ethical Concepts

  • Support students in exploring bioethical issues. Provides to what extent the outcome is ethical.
  • integrity- search for knowledge and honest understanding: permission and scrutiny is ensured, along with public knowledge
  • justice- ensuring there is fair consideration. That no action causes burden and fair disribution.
  • non- maleficence: avoids harming- resulting from posititions should not disproportionately damage actions.
  • errors- dont be confused with personal measures and error.
  • Errors are the differences from what is true value and being measured. Consists of systematic ways of data.

Area of Study 1: Molecular Life

  • Expression of the information encoded in a sequence of DNA to form a protein is studied.
  • Molecular techniques are shown for application. As well, gene tech is also comparitively studied against agriculutre/ ethical implications

Outcome 1

  • Students should be able to: relate nucleic acids and proteins as well as apply techniques that are used with the manpiulation of DNA!!
  • They can use knowle dge from past areas of study to help them attain better knowledge and attain previous science skills on specific pages 7-9. This leads to studying these as main skills

Key Factors

  • Know that nucleic acids act as building blocks to the protein synthesis to the structure to code genetic material properly. There is also the regulatory elements (operon) Proteins are as monomors in levels and cellular processes, and can help in the export of proteins from a cell via secretory pathway DNA has its own manipulation technqiues: using polymerases and using Crispr-9 like elements. There is amplication of this polymerase DNA in recombinant
  • GMOS are to improve and increase for resistance also in agriculture.
  • There is always a need to focus on photosystem for the students, where factors that can impact such an enzyme have a function with respiration. There are also cells that respire at the beginning.
  • With it are key things such as fermentation in animals*
  • For it is important/ critical about CRISPER with technqiues

AREA- assessment.

  • This a the award is based on the demonsatred outcomes. To show skills the students use a variety of leanring activities and assemsnt tasks.
  • This all comes to desgn activities and is part of class and the time table. There is 2 levels: scholl, the amount for coursework. These are regular and do apply, with options for schools. In it there is. Advice.
  • the tasks must be comapable when setting. For unit tasks there select. From for outcomes 1-2 there is list, case study, bio informatics, report, poster etc. and you can not select more than it.

AREA Unit 4: The study of what ife changes to respond to challenges

  • The unit is set to provide continual help to respond and what life must face. Student study human defence, system, and immunity alongside how knowledge assists with problems facing ethical diseases
  • how can new evolutinary techniques assist what is known? and what challenges comes with it? data, analyse bio ethical -What do we do! This includes things such as cancer and allergies, and therapy development to combat for prevention as a factor. The study then asks the question for what new knowledge to use to consider these aspects.

The VCE then implements

  • "ethical concepts"- they set out the key values and ethical concepts. Also with a focus on student skill.
  • A student may have to get creative with their own key knowldge/ study

What is to be done

Student needs to understand + adapt what helps life changes and responds in posters (with results etc/ key findigs/ conclusion)

Key note - areas for study

How do people deal with pathogens

  • Defence to immune, immunity what plays a part.
  • They explain assistant managment/ technological advances as well

The student then may analyse the immune

  • The relate key is to improve scinece

  • there comes a study. To which the key nowledge plays parts in the study

  • Students are also given: knowdge, responses, ability etc

  • In the modern/ current world (the "study design")- there are also biological chaallenges. the prevention, medical field

At the end of it all

  • Students show be able to identify and compare key ways, and work out chaallenges in order to give responses and help with the area/ treatment of disease.

So what "Key knowdelge is"

  • The response
  • The "immune respone"- inflammatry cells and steps to attack
  • to help and support antigen

Note key areas for this

  • system transports
  • t and be limits. The action to use and the passive ones.
  • Themergence, sociality, controllig spread
  • How to use vaccine support
  • the process of improvement also happens

Another "area of key knowledge"

  • How are species related? and what are their challenges?
  • In are of what to study/ the students relate their science to "material overtime and their evoltion
  • they use the information to determine the relatedness

Outcome - to see what genetic changes does a species have overtime

  • They have the science and data analysis to help make their data/ decisons

Main parts- what we need in order

  • Causes that chagnve, and consequences -Manipulation is possisble- there is data and analysis to show it to improve how the study does, to better.
